iiViPROVEMENT IN SASH-HOLDERS.

Specification forming part of Letters Patent No. 165,759, dated July 20,1875; application filed June 2, 1875.-

To all whom it may concern: 7

Be it known that I, OLIVER ROCK, of Hudson, in the county of Middlesexand State of Massachusetts, have invented certain Improvements inWindow-Sash Supporters, of which the following is a specification:

In the accompanying drawing, forming a part of this specification,Figure 1 is a view of the lower sash of a window and its casing, showingthe application of my invention in section. Fig. 2 is an enlargedsectional view of my invention, and Fig. 3 an end view of the same.

This invention relates to that class of sashsupporters in which afriction-roller is held by spring'pressure against the edge of the sash,therehy supporting the sash at any desired height, and preventing itfrom rattling; and it has for its object to provide cheap, simple, andconvenient means for applying supporters of the above-named class to awindowcasing. Tothis end my invention consists in a recessed cylindricalholder, having a spiral spring, a concave-faced pressure-block, and aloose friction-roller, and adapted to be inserted into an auger-holebored into the windowcasing in such manner as to cause thefrictionroller to bear against the edge of the windowsash, as I will nowproceed to describe.

In the drawing, A represents the lower sash of a window, and B thecasing. G C represent the sash-supporters, each of which is composed ofa cylindrical recessed holder, (Z, a spiral or other spring, 6, asliding pressureblock, f, and a friction-roller, g, these parts 7 beingarranged in the recess h of the holder (1, as shown in the drawings. Theholder d has a head or flange, d, on its outer end, and is inserted intoa circular orifice bored in the window-casin g B, said orifice beingpreferably reamed out at its outer end to receive the head or flange d,which prevents the holder from entering the orifice too deeply.

Two of the supporters O are supplied for each sash, and they are locatedone on each side of the sash, with their rollers bearing against thelatter, as shown in Fig. 1. The

supporters of the lower sash are preferably applied to the window-casingon the same horizontal plane as the upper rail of the sash, as shown inFig. 1, the supporters of the upper sash being on the same plane as thelower rail thereof. The inward pressure of the rolls supports the sashesat any point, as will be readily understood.

The recess h of the holder d is of such size as to permit the freemovement of the pressure block and roller, and these parts, togetherwith the spring, are merely inserted in the recess without beingattached in any way to the holder or to each other; consequently, eachor all of them can be removed from the holder in case the roller andpressure-block become worn, or the spring weakened or broken.

This device can be applied by an ordinary mechanic to awindow-casingwithout difficulty or nicety of adjustment, it being only necessary tobore holes in the casing for the reception of the cylindrical holders.

Different springs can be applied to the same holder proportioned instrength to the weight of the sash, and the holder with its attachmentscan be sold ready for application by the hardware trade.

The invention is applicable particularly to car-windows, as it isadapted to prevent the sash from rattling, as well as to support it.

If desired, the supporter can be applied to the sash instead of thecasin g, without departing from the spirit of my invention.

I claim- In a sash-holder, the combination of recessed holder (1, spring6, concave-faced pressure-block f, and loose friction-roller g,substantially as shown and described, for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

OLIVER i soon.
